    Abstract: The present invention concerns a method and a device for controlling the voltage of a catenary supplying electric power to rolling stocks. The first rolling stock: —detects a traction command or a regeneration command of a second rolling stock in the neighborhood of first rolling stock, —increases the electric power supplied by the first rolling stock to means for heating, ventilation and air conditioning when a regeneration command of the second rolling stock is detected, —decreases the electric power supplied by the first rolling stock to the means for heating, ventilation and air conditioning when a traction command of the second rolling stock is detected.

    Abstract: In the case that an auxiliary such as the air conditioner is operated with electric power from the commercial power supply by controlling the charger prior to the system startup and the inter-terminal voltage of the battery is more than or equal to the threshold value Vref that is a voltage where there is a possibility of overcharging the battery when the battery is charged, the supply voltage of the electric power supplied from the charger is set to the voltage that is a little smaller than the threshold value, and the auxiliary is operated with the electric power from the battery and the electric power from the charger. This arrangement enables to prevent overcharging the battery and to operate the auxiliary in the case that an auxiliary such as the air conditioner is operated with electric power from the commercial power supply by controlling the charger prior to the system startup.

    Abstract: In a power supply system, a controller is electrically connected with a plurality of switching elements of a multiphase inverter. The controller switches the plurality of switching elements on and off during a multiphase motor being activated. This converts a voltage of a first power storage device into a multiphase AC voltage so as to supply the multiphase AC voltage to the multiphase motor. This also boosts a voltage of a second power storage device to charge the first power storage device by the boosted voltage via multiphase windings of the motor. The controller switches the plurality of switching elements on and off during the multiphase motor being inactivated to thereby boost the voltage of the second power storage device to charge the first power storage device by the boosted voltage.

    Abstract: A regulator includes a power-converting circuit and a protection circuit. The power-converting circuit is for converting a primary voltage to a secondary voltage. The protection circuit is coupled to the power-converting circuit. The protection circuit receives the primary voltage earlier than the power-converting circuit. When a voltage spike of the primary voltage occurs, the protection circuit shunts the high instantaneous voltage to ground. An electrical device and a car using the regulator is also provided.

    Abstract: An open forklift truck is provided having an elongated windshield that protects the operator from wind chills experienced when operating the truck in a cold storage environment. The windshield is a laminate having a plurality of heating elements disposed therein that are electrically connected to a control that monitors speed, battery voltage, temperature, and ambient feedback and adjusts the power supply to the windshield based on this feedback. Accordingly, the windshield is maintained at a predetermined temperature selected to limit condensation and fogging of the windshield.
